Description
Technical field
This utility model relates to chemical industry technical field of organic silicon production, specifically a kind of organosilicon fluidized bed reactor distribution device in gas-fluid.
Background technology
The features such as organosilicon material has the high-and low-temperature resistance of excellence, biocompatibility, can be widely applied to the fields such as industry, agricultural, military project, enjoy the good reputation of " industry monosodium glutamate " in industrial quarters.Fluidized-bed reactor is one of nucleus equipment of organosilicon production, gaseous chlorine methane is entered by fluid bed low head, through distribution device in gas-fluid laggard fluidized bed inside reactor, the solid particulate matter such as silica flour and catalyst is made to be in fluidized state, generation gaseous organosilicon monomer is reacted under about 300 DEG C temperature conditionss, therefore, distribution device in gas-fluid will directly affect fluid bed fluid effect, and then affect reaction rate and yield.
At present, the organic silicon fluidized bed distribution device in gas-fluid of ton run outside Present Domestic sums up and is divided into two classes: a class is the flat board distribution apparatus of blast cap side opening；One class is the conical distribution device of blast cap side opening.Chinese patent CN 201969549U describes the distribution device in gas-fluid of a kind of fluidized-bed reactor for organic silicon monomer synthesis, and this device uses several layers of porous flat plate distribution grid superposition to arrange, arranges rustless steel Graphite pad between each plate, and pore staggered floor is arranged.This device effectively reduces the probability that aperture on distribution grid is completely plugged, processes simple, easy to maintenance, but owing to each layer distribution grid local resistance differs, after superposition, resistance increases, and the probability of gas generation bias current is bigger, in addition, during fluid bed parking maintenance, it is necessary to tear bed open and clear up this distribution apparatus；Chinese patent CN 201140063Y describes the bipyramid flow-guiding type air inlet distribution apparatus of a kind of organic silicon monomer fluidized bed reactor, uniform sieve aperture is had on this distribution apparatus inner cone sieve plate, overlap an outer cone-plate outside cone sieve plate again, above set pod apertures, it is ensured that interior cone-plate side pressure is homogeneous.This distributor gas is evenly distributed, and fluidization quality is good, but after expanding production, owing to air inlet is few, there may be gas pressure heterogeneity inside bicone, affect fluidization quality, during parking maintenance, it is also necessary to tears bed open and clears up this device.
Summary of the invention
The technical problems to be solved in the utility model be to provide a kind of air velocity uniformly, gas not bias current, the organosilicon fluidized bed reactor distribution device in gas-fluid of the advantages such as fluidization quality is high, be not easily blocked.
In order to solve the problems referred to above, the technical solution of the utility model is: a kind of organosilicon fluidized bed reactor distribution device in gas-fluid, two pieces of gas distribution grids including tapered layout, on every piece of gas distribution grid, distributing installation has many chloromethanes air inlet pipe, a blast cap it is mounted in the upper end of every chloromethanes air inlet pipe, blast cap has the brim of a hat downwardly extended, being constituted a gas passage excessively communicated with chloromethanes air inlet pipe by the brim of a hat of blast cap with chloromethanes air inlet pipe tube wall, this crosses the outlet side of gas passage towards gas distribution grid.
Further, chloromethanes air inlet pipe passes gas distribution grid away from one end of blast cap, extends to the side of gas distribution grid, is connected with one and is shaped as flaring air inlet on the end of the side that chloromethanes air inlet pipe extends gas distribution grid.
Of the present utility model has the beneficial effect that the two pieces of gas distribution grids ratio using tapered arrangement uses flat gas distribution grid to increase gas passing area, improves gas efficiency and fluidization quality；Gas passes through chloromethanes air inlet pipe from crossing ejection gas passage, the gas crossing the ejection of gas passage can blow to gas distribution grid, gas enters in fluid bed tank body after being broken up by the block of gas distribution grid again, and then makes the gas can be in more uniform and then fluid bed tank body；Blast cap can block the powder in fluid bed tank body and enter in chloromethanes air inlet pipe, it is to avoid causes the phenomenons such as fluid bed bias current because of blocking in production process, extends the production cycle, and parking can not also tear bed cleaning open, for repeatedly driving continuously to provide probability.
On the other hand, flaring air inlet can make gas be more prone to concentration to enter in chloromethanes air inlet pipe, improves intake efficiency；The end face of blast cap is sphere, reduces the gas flow-disturbing in blast cap right angle, and the gas being can be discharged more smoothly.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings this utility model is described further:
Fig. 1 is structural representation of the present utility model,
Fig. 2 is the schematic diagram of the structure that this utility model improves,
Fig. 3 is this utility model structural representation in use.
Detailed description of the invention
If Fig. 1 is to shown in 3: a kind of organosilicon fluidized bed reactor distribution device in gas-fluid, two pieces of gas distribution grids 1 including tapered layout, on every piece of gas distribution grid 1, distributing installation has many chloromethanes air inlet pipe 2, a blast cap 3 it is mounted in the upper end of every chloromethanes air inlet pipe 2, blast cap 3 has the brim of a hat 32 downwardly extended, blast cap 3 is fixedly connected on one end of chloromethanes air inlet pipe 2 by support bar 4, be made up of with chloromethanes air inlet pipe 2 tube wall the brim of a hat of blast cap 3 one communicate with chloromethanes air inlet pipe 2 cross gas passage 31, this crosses the outlet side of gas passage 31 towards gas distribution grid 1.
This utility model can also do and improve as follows:
Further, chloromethanes air inlet pipe 2 passes gas distribution grid 1 away from one end of blast cap 3, extends to the side of gas distribution grid 1, is connected with one and is shaped as flaring air inlet 21 on the end of the side that chloromethanes air inlet pipe 2 extends gas distribution grid 1.
Further, the end face of blast cap 3 is sphere.
When actual production, the width crossing gas passage 31 can be 2 ~ 15mm, highly more than 200mm, and between the angle between two pieces of gas distribution grids 1 can be spent 90 to 160, the diameter of blast cap 3 can be 25 to 40 millimeters, high 250 to 300 millimeters, wall thickness 5 to 8 millimeters.
Time specifically used, silica flour enters in fluid bed tank body 5 from silica flour conveying pipe 7, and methyl chloride gas is entered in the cavity 51 of fluid bed tank body low head by chloromethanes feed pipe 6, enters in fluid bed tank body 5 by crossing gas passage 31, makes into a silica flour fluidization.
Two pieces of gas distribution grids 1 ratio using tapered arrangement uses flat gas distribution grid 1 to increase gas passing area, improves gas efficiency and fluidization quality；Gas passes through chloromethanes air inlet pipe 2 from crossing ejection gas passage 31, the gas crossing gas passage 31 ejection can blow to gas distribution grid 1, gas enters in fluid bed tank body 5 after being broken up by the block of gas distribution grid 1 again, and then makes the gas can be in more uniform and then fluid bed tank body 5；Blast cap 3 can block the powder in fluid bed tank body 5 and enter in chloromethanes air inlet pipe 2, avoid and production process causes because of blocking the phenomenons such as fluid bed bias current, extending the production cycle, parking can not also tear bed cleaning open, for repeatedly driving continuously to provide probability.
On the other hand, flaring air inlet 21 can make gas be more prone to concentration to enter in chloromethanes air inlet pipe 2, improves intake efficiency；The end face of blast cap 3 is sphere, reduces the gas flow-disturbing in blast cap right angle, and the gas being can be discharged more smoothly.
